CVE-2024-11534

Code execution via unchecked DXF buffer read

Published Nov 22, 2024 · Updated Nov 22, 2024

Out-of-bounds read in IrfanView 4.67 allows remote attackers to execute code by inducing a user to open a crafted DXF file. The DXF parser fails to validate user-supplied data before reading beyond the end of an allocated buffer. Execution requires a user to visit a malicious page or open the file, and code runs in the current process context.
